Sharing improvements

I have a couple of small nits (not sure if you would consider them bugs) regarding sharing a spreadsheet (probably applies to sharing in general):

- It would be nice to share a document with people, without sending an email--perhaps just give a link that I can paste to them, or just have them be able to log in and see the shared document without getting an email from Zoho

- If I want to update the permission of a shared spreadsheet for a specific person, I need to update each page separately. It would be nice to be able to update the permission with respect to the user instead of the workbook (similar to how you can do it when you initially share a doc with someone)

- The notification email should go out with either my full name or my nickname (ideally, my choice), but definitely not my login id in the from field as it currently does. ex:

Current email:
From: login <email@address>
Desired email:
From: "Full Name" <email@address>

Also the email should be selectable in the event that there are multiple email addresses associated with an account. Some of the people I interact know my by one email address, others by another.

- Also regarding the notification email, with the increasing popularity of DKIM, DomainKeys, SPF, and other sender verification methods, it is probably wise to send the email from an address at your domain, and set the reply-to as my email address.

Keep up the great work on your product!
